How I collected my 60 PDUs
After revision in March 2011, PMP PdU collection has become very easy. You can claim 30 PDUs for self directed learning (earlier it was 15 PDUs) and 15 PDUs in 3 years for PM Practioner. Assuming most PMPs are practicing PM profession, getting 45 PDUs is cake walk . So you just have to worry about the remaining 15 PDUs.
1. I had developed a 1/2 day course in my company, for which I got 16 PDUs.
2. I had taken a class on the above course for 4 hours.
So easily I could claim 20 PDUs, I had attended some PMI sessions and that was bonus.
So most people can now focus on getting 15 PDUs, but since you can transfer 20 PDUs to next cycle, its advisable that you take a course which offers 30-40 PDUs, that way you dont have to worry for 6 years.
I strongly advise PMPs to keep their certification valid as you never know when it will come handy. PMP is becoming defacto rule for hiring laterals in many organizations.
